ADAGUC is about…
� Connecting atmospheric- and geosciences
� Atmospheric datasets in GIS systems
� Open standards � OGC� Web Mapping Service – For visualization
� Web Feature Service – To retrieve vector data
� Web Coverage Service – To retrieve raster data
� Knowledge & technique dissemination

NetCDF4 as data carrier
� Joint project between Unidata and HDF Group
� NetCDF 4 uses HDF5 as the storage layer of NetCDF
� Programming interfaces are backward compatible with the netCDF3 programming interface
NetCDF3popular, simple, lots of tools,
multiple implementations
HDF5powerful, high-performance,
storage efficiency, extensibility
NetCDF4
Best of both formats combined!

i.nl GDAL/OGR drivers
Open source translator library for raster geospatial data formats
Used in many software productsUMN MapServer, GeoServer, Quantum GIS, ArcGIS, GRASS, OpenEV etc..
GDAL - Geospatial Data Abstraction Library
� Access raster data
OGR - Simple Feature Library
� Access vector data
GDAL/OGR extensions for the ADAGUC format standard are available:

� Obtaining the real data through OGC services or the original ADAGUC (NetCDF/HDF5) files
� WFS or WCS ?
� WebGIS client selects the appropriate service depending on the datatype (raster/vector)
� WCS – obtain optimal parameters:
� Predefined bounding box, columns, rows and cell size
� No resampling/interpolation
User is always free to adjust the parameters
� User must select his favorite (GIS) format

Summary
� Product standard is stable.
� Much experience gained with GDAL/OGR, NetCDF/HDF5, INSPIRE, OGC, UMN MapServer
� Portal and services are ready:� Satellite, model, and radar datasets are
available and more will follow.
� Next challenges:
� Start using catalogue services (CSW).
� Data policies, operational status.
� 4 dimensional data.
� Client applications should work on supporting the OGC standards.
